将JObject转换为强类型对象 [英] Convert a JObject to a strongly typed object

问题描述

我正在使用JsonConvert从这样的类对对象进行序列化和反序列化:

I'm using JsonConvert to serialize and deserialize objects from classes like this:

public class DbBulkRequest
{
    public DbEntity[] Updates { get; set; }
}

public class DbEntity
{
    public string Name { get; set; }
    public object Dto { get; set; }
}

反序列化Dto时，会得到一个JObject类型的对象.在反序列化时，我想基于Dto创建强类型的对象.我可以创建对象；但是，我不知道填充其属性的好方法.我发现最好的就是这种芝士球方法:

When I deserialize Dto, I get an object of type JObject. At the time of deserialization, I want to create strongly typed objects based on Dto. I can create the objects; however, I don't know of a good way of populating their properties. The best I've found is this cheeseball approach:

MyEntity e = JsonConvert.DeserializeObject<MyEntity>(JsonConvert.SerializeObject(dto));

什么是更有效的解决方案?

What would be a more efficient solution?

推荐答案

添加 TypeNameHandling

private readonly JsonSerializerSettings defaultSettings = new JsonSerializerSettings
    {
        Formatting = Formatting.Indented,
        TypeNameHandling = TypeNameHandling.Auto
    };

这里是例子

private readonly JsonSerializerSettings defaultSettings = new JsonSerializerSettings
    {
        Formatting = Formatting.Indented,
        TypeNameHandling = TypeNameHandling.Auto
    };

[Fact]
public void Test()
{
    var entity = new DbEntity
        {
            Dto = new TestDto { Value = "dto" },
            Name = "Entity"
        };
    string serializedObject = JsonConvert.SerializeObject(entity, defaultSettings);
    var deserializedObject = JsonConvert.DeserializeObject<DbEntity>(serializedObjest, defaultSettings);
}

public class DbBulkRequest
{
    public DbEntity[] Updates { get; set; }
}

public class DbEntity
{
    public object Dto { get; set; }
    public string Name { get; set; }
}

public class TestDto
{
    public string Value { get; set; }
}
